The showdown of lightweight strikers serves as the latest addition
to the July 6 bill, which is topped by a middleweight title
showdown between longtime champion Anderson
Silva and unbeaten challenger Chris
Weidman. The pay-per-view event takes place at the MGM Grand
Garden Arena in Las Vegas and will also see Chan Sung
Jung square off with Ricardo
Lamas in a pivotal featherweight pairing.

Barboza, meanwhile, returned to action on Jan. 19 after spending
eight months on the shelf following an upset knockout loss to
former WEC champion Jamie
Varner. The native Brazilian responded to his first defeat by
posting a one-sided win over countryman Lucas
Martins, stopping the previously unbeaten prospect in just
2:38.
